FUNCTION
The new ultra low-profile Magnetic Vacuum Breaker by Girard, is a valve designed to limit a negative pressure (vacuum) in a typical tank trailer.
This model has a 3” NPS swivel connection and stands less than 4” tall when installed on a typical tank nozzle making it easy to install under already existing overturn protection.
Customers interested in purchasing the older MC307 style 3MVB may want to consider this new model which is lower in cost and will provide an increased flow rate of the 3MVB.
Part Number: GIR 3X407MVB-UT
